. TAB FOR PLAYER ROLLS.

Specification of Letters Patent. Patented D1211. 21, 1922.

Application filed February 28, 1921. Serial No. 448,674.

mechanism wherein an extension operates in conjunction with asecuring ring to facilitate connection of the web of the player roll' to the receiving spool.

In the present state of theart, apertured rolls for player pianos are provided with pointed ends to the apex ofwhich is secured a tab having aring therein for engagement with a hook upon the receiving spool ofthe player mechanism.

This receiver spool is located close under the tracker board and when placing the ring of the tab in connection with the hook of the receiving spool said tab isso extremely short that an undue pressure and strain is applied to one of the inclined sides of the pointed end of the web or player roll so that said edge becomes easily and quickly torn in such a manner that it must be secured by pasting reinforcing webs on each side thereof. The additional thickness thereby provided has a tendency to prevent proper establishment of the web upon the receiving spool.

The present invention has for its object the provision of a new article of manufac ture comprising a tab having an extension of: sufficient degree to permit threading and attachment of the web or player roll over the tracker board of a player piano and onto the hook or the receiving spool without bringing undue strain and stress upon one edge of the paper by the hand of the operator during such threading process.

A further object of the invention is to provide a simple and effective means for attachment onto present webs or player rolls as well as those which may be constructed hereafter.

A still further object of the invention is to provide a tab which may be easily at tached to the end of a player roll and arranged to facilitate the threading and connection thereofto the receiving spool with-5 out producing undue stresses andstrains on the adjacent edge of the web by the hand of the operator during such threading and connecting process. I

7 It is also an object to provide an improved device of the character described wherein th tab is arranged to be enclosed within the periphery of the receiving spool to permit proper establishment of the web upon said receiving spool.

I. accomplish these and other objects by means of the improved device disclosed in the drawings forming a part of the present specification, wherein like characters of rei erence are used to designate similar parts throughoutthe said specification and drawings, and in which v Fig. l is a view of the end of a web or player roll attached to a receiving spool of a'player piano; and

' Fig. 2 is a transverse sectional view taken through the approxlmate center of the recelving spool and disclosing a side elevation of my improved tab as applied to the end of the web or player roll.

Referring to the drawings, the numeral 1 is used to designate the end of a web or i it player roll having the usual beveled. edges Q'by means of: which a point is produced on the forward or front end of said roll, as disclosed in dotted and full lines in Fig. 'l. of? the drawings.

The dotted lines are used to indicate the present arrangement wherein the fingers or hand. of the operator, beardirectly, and with pressure, against one of the beveled edges 2 which always results, within a comparatively short time, in a fracture or tear in said edge, as disclosed in dotted lines at 3. in Fig. 1 of the drawings.

Th edges of this fracture or tear generally turn under the web or player roll .1.

which prevents an oven establishment of suc- ('fGSSlVll-l layers of said web. upon the receiving spool l. which even establishment is not only essential to the operation of the web 1 but is also necessary for its preservation.

This undue stress and strain is the result of the close relation lrietwcen the receiving spool i and the tracker board. not shown. resulting in a lack of space which. is further aggravated by the engaging hook 6 within the annular recess 7 usually provided, within the approximate longitudinal center of such spools 4. By reason of this close arrangement of the parts of. the player there is insulficient room for the hand of the openator to properly engage and manipulate the end of the web or player roll 1 and to secure the ring attached thereto without exposin the beveled edge 2 to the destroying pressure from the hand of the operator-as illustrated in dotted lines in Fig. 1 oi the drawings.

In my improved tab for player rolls have provided a member having two body portions 8 connected. by a web 9 which is bent upon itself to provide a loop for the engagement of a suitable metallic ring .11 and to bring into registration or juxtzu osition the body portions 8 on each side oi the point oi the web or player roll l.

The body portions 8 are further provided with diverging wing portions 12 which are arranged to extend along the beveled edges 2 ol the web 1 aconsiderable distance "from the point thereof so as to reinforce said beveled edges 2 and thereby reduce liability to fracture.

The adjacentlfaces ot the wii .1 and body portions 8, well as the adjatent .i'aces of the extension 5-), are giunmed so that said portions '8 and 12 may be readily and lirinly secured to the point of the web 1, and also to more firmly connect the double layer 0ft the extension into a single member thereby providing greater etlieieney and strength to said extension 9.

It is obvious that the tab disclosed in the present specification may easily replace a tab of the shorter type by trimmingoil? the end of the web 1 to procure new iaterial to which said new tab may be attached.

It is also obvious that with the extension 9 the process of threading and securiing the end of the web 1 to the receiving roller is will be greatly facilitated without exposing said web to undue strain and stress which would otherwise tend to fracture the same.

As the receiving roller 4 is rotated it is evident that the extension will be wound within the annular channel or recess 7 and thereby preventunevenness of the roll as established or formed upon said receiving roller l.

.l'lavingthus described my invention, what I claim new and desire to secure by Letters Patent is:

l. A tab for player rolls comprising a body portion having diverging wing portions, said body and wing portions being arranged to engage the point and beveled sides adjacent said point, of the end ol" :1 player roll for player pianos, and l kewise provided with an elongated extension formed) integral. therewith; and means secured to the extension fordetachably connecting the same to the receiving spool ot a player piano.

:2. A tall) for player rolls CUULPYlSlHg a body portion lnrving diverging wing portions, said bodyand wine portions beinn' e'un'nned on their adjacent faces to engaor ,both surfaces of the point ,and beveled sides ad acent the point of a player roll 'lor player pianos, said body portions beinr (-onuerted by an extension bent upon itselil to term an elongated loop; ztll'ltl a suitable ring mounted within the loop whereby the end o'l said extensionmay be-detaehably connected to a receiving spool for player ,pianiis 8. A tab tor player rolls comprising body portions havingdiverging wing poi-thins, sald body portions being connected and brought into juxtaposition by a COlH'lQC-illlll portion. bent upon itself to form an exten :sion tosaid portions and an elongated loop. vthe adyacent sides of said body, wineportionsand extension being guinmcd wherebv said body and wing portions may engage opposite surfaces of the end ol a player roll For player pianos; and a suitable ring:

gmountod within said loop whereby said roll may be detachahly (fOHlltCl'Qtl to a receiving spool :l'or a player piano.

In witness whereot' l hereunto set my signature.
